Abstract

An electronic device may be provided with a housing having sidewalls, a dielectric cover, and a conductive plate. A display may be mounted to the sidewalls opposite the dielectric cover. A logic board may be interposed between the display and the plate. The device may include a phased antenna array on a first module and an ultra-wideband (UWB) on a second module. The first and second modules may be surface-mounted to the main body of a flexible printed circuit between the plate and the dielectric cover. The UWB antenna and the array may convey radio-frequency signals through the dielectric cover. The flexible printed circuit may have a tail that carries the transmission lines for the UWB antenna and the array. The tail may be folded through a hole in the mid-chassis and coupled to a radio-frequency connector on the logic board.
